Bobbins (Coil Formers), Mounts, Hardware

1. What are Bobbins/Coil Formers?

They are the core components of transformers, used to secure the coils and core. Typically made of plastic or resin, they provide insulation and mechanical support, directly impacting transformer performance and safety. Common types include:

EI Type: Constructed from “E” and “I”-shaped laminations with a central gap, suitable for designs requiring a clear magnetic flux path.

EE Type: A gapless lamination structure improves magnetic flux efficiency, making it suitable for high-efficiency transformers.

Other Types: Such as EF, ER, and RM, are optimized for different applications, such as high-frequency power supplies or industrial controls, based on their shape.

2. What are Mounts?

Refers to fixtures (such as brackets or mounting plates) used to secure the bobbin or coil in place within the equipment. In this patented design, the bobbin utilizes radial protrusions or lugs on the base to engage with the support plate. Rotating and locking prevent displacement, making it suitable for automated production lines or high-frequency winding machines.

3. What is Hardware?

This includes connectors, fasteners, and auxiliary components that enable mechanical integration and reliable connections in electronic systems. For example, relays and solenoid valves control circuit switches, and power management modules (such as voltage regulators) ensure a stable power supply. These hardware components work in conjunction with the circuit board to improve device durability.
